Hi TI,
I design one ADS42JB46 Test Board following the official design 'ADS42JB46EVM'.
Now I want to test the performance(ENOB) of ADS42JB46 chip.
I want to test ENOB under several specific frequency as the you do, so I can compare my results with the official results.
Q1: I need to know which Frequency is the Reference because I only find one frequency input for ENOB test in ADS42JB46 datasheet.
And I find several frequency input for SNR test:
So I should test under 10MHz/70MHz/170MHz/230MHz ?
Q2: By the way, I want to choose one good Narrow band pass filter(for SINGLE FREQUENCY PASS) to filter noise because my Anolog-Source is not good, which Filter may I use?
Best Regards,
Nan
